Subject: [PATCH v6 06/21] arm64:uapi: set __BITS_PER_LONG correctly for ILP32 and LP64
Date: Thu, 14 Jan 2016 20:23:03 +0300 [thread overview]
Message-ID: <1452792198-10718-7-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1452792198-10718-1-git-send-email-ynorov@caviumnetworks.com>
From: Andrew Pinski <apinski@cavium.com>
Define __BITS_PER_LONG depending on the ABI used (i.e. check whether
__ILP32__ or __LP64__ is defined). This is necessary for glibc to
determine the appropriate type definitions for the system call interface.
